Resistant Starch

Resistant starch is a type of dietary fiber that can be found naturally in foods (e.g., legumes, whole grains, potatoes, underripe bananas) or taken as a supplement. Resistant starch acts as a food source for microbes in the gut, which can stimulate the growth of potentially beneficial bacteria and lead to the production of short-chain fatty acids. While this might lead to positive effects both locally in the gut and for overall health, clinical trials tend to report inconsistent results and any benefits seem to be small in magnitude.
